Description
Technical field
The utility model relates to the interlock Obstruct apparatus in a kind of coal mine lower railway transport systems, relates in particular to the chain stop device of a kind of automatic pneumatic type.
Background technology
In the rail transport process of mine, the winch that becomes hillside fields point promotes and occupies a large amount of proportion.Point will be provided with the facility of holding up traffic accordingly in the change hillside fields, prevents that vehicle from by gallery the sport car phenomenon taking place in the transportation of inclined gallery, and a second class protection device is set, and meets accident when preventing the transportation of the flat inclined gallery of track, causes the generation of unpredictable accident.Used Obstruct apparatus, the grade change point in gallery and inclined gallery is provided with the track Obstruct apparatus, connects locking mutually between the twice Obstruct apparatus with rope.Between connection cord, add a long-armed trip gear, will manually pull long-armed device when needing the stop device action and start the closing appliance of holding up traffic.Trip gear is near apart from track, and vehicle will be absolutely unsafe by staff's process at one's side when personnel pulled long-armed device.And connect with the hairspring rope between trip gear and the track Obstruct apparatus, be easy to the track Obstruct apparatus takes place because a variety of causes is not in place and because the distortion in tunnel causes the not smooth of connecting device, very easily have an accident.
Air door is to cut off the ventilation structures that distinguished and admirable pedestrian again is open to traffic simultaneously.In the coalmine ventilation system, play crucial effects.In the management of the air door that is open to traffic, vehicle hits the phenomenon ubiquity that air door causes air door to damage when not opening air door, this not only is unfavorable for safety but also is unfavorable for keeping the intact of mine ventilation facility, break the maintenance period at air door, the stable of ventilation system can't guarantee, very easily cause a serious accident, threaten and influence the ordinary production of mine.
Summary of the invention
The purpose of this utility model is exactly that vehicle by gallery sport car, injury personal safety and the easy impaired phenomenon of air door takes place easily when transport inclined gallery in the present coal mine lower railway transportation in order to solve, produce the problem that causes potential safety hazard to the colliery, provide a kind of have simple in structure, easy to use, can realize the chain stop device of automatic pneumatic type of advantages such as safe and reliable transportation.
For achieving the above object, the utility model has adopted following technical scheme:
The chain stop device of a kind of automatic pneumatic type, it is installed in change hillside fields point that gallery and/or inclined gallery intersect or on the track of air door both sides, it comprises at least one pair of stop device, every pair of stop device is made up of cylinder and a pair of block, wherein cylinder is positioned under the track, block is connected with the two ends of cylinder, and cylinder also is connected with central controller, and each is to locking connection mutually between stop device.
Described stop device is provided with two pairs at the flat slope point and/or the slope point of track grade change point; Stop device at flat slope point is a normally off, is normally open at slope point stop device, and cylinder is promoted by mine compressed air machine source of the gas, and two pairs of mutual lockings of stop device.
Described stop device is arranged on apart from each 2.5m place, air door both sides, is symmetric offset spread in orbit, highly for exceeding rail level 200mm, and two pairs of mutual lockings of stop device.
Described locking is connected to, and each is controlled by same source of the gas stop device, a pair of stop device locking, and another is opened stop device, forms mutual locking.
Stop device of the present utility model is divided into two kinds of installation sites, and they use in pairs, be installed on the respective track, and locking mutually.
The beneficial effects of the utility model are: simple in structure, easy to use, safe and reliable, can effectively prevent the generation of accident.
Description of drawings
Fig. 1 is the structural representation of stop device;
Fig. 2 is the structural representation when being installed in the change hillside fields point that gallery and inclined gallery intersect;
Fig. 3 is the structural representation when being installed in the air door both sides.
Wherein, 1, block, 2, cylinder, 3, track, 4, stop device.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Among Fig. 1, stop device 4 is made up of a pair of block 1 and the cylinder 2 that is attached thereto, and their mounted in pairs are on track 3.Cylinder 2 is connected with controller.
Embodiment 1:
Fig. 2 is the structural representation that the utility model is installed at the change hillside fields point of gallery and inclined gallery intersection.
When 1, being installed in roadway slope change point
(1), external source of the gas: mine compressed air machine source of the gas, supply gas pressure can start this system more than 0.2MPa.
(2), at the signal chamber pneumatic stop device control system K is installed.
(3), in track flat slope section normally closed stop device A is set.
(4), be provided with in track slope section and often open stop device B.
(5), system's air feed bleed pressure is more than 0.2MPa.
The operating procedure of device:
The virgin state of A, device:
(1), the master cock K of pneumatic stop device is in state to be excited.
(2), flat slope section stop device A is in closure state.
(3), become the slope pneumatic stop device B of section and be in open mode.
B, when the vehicle pine falls:
Prepare Song Jiangshi to the track pittop when vehicle operating, personnel pin the master cock K of pneumatic stop device after the signal chamber sends loose car signal, open flat slope section stop device A, allow vehicle slowly pass through, become the pneumatic stop device B closure of slope section this moment, prevent from that vehicle from meeting accident to slide track.This moment, vehicle was slowly loose down under the control of winch, after vehicle passes through flat slope section stop device A, unclamped the master cock K of pneumatic stop device, became the slope pneumatic stop device B of section and opened, and allowed vehicle pass through smoothly.This moment, each control convenience of system was got back to virgin state.
C, when vehicle promotes:
When vehicle promotes adjacent tracks the higher authorities, meet accident by grade change point for preventing vehicle, after vehicle is by the pneumatic stop device B of change slope section, start the master cock K of pneumatic stop device, become the pneumatic stop device B closure of slope section this moment, play the effect of holding up traffic, prevent the vehicle slip-down lower railway.Flat slope section stop device A opens, and allows vehicle pass through smoothly, after vehicle passes through flat slope section stop device A, unclamps master cock K.Each function unit reduction of system this moment.
Embodiment 2:
It among Fig. 3 the structural representation that is installed in the air door place.
Stop device is arranged on apart from each 2.5m place, air door both sides, is symmetric offset spread in orbit, highly for exceeding rail level 200mm.
